> {Edit} Ha, looking at the competition, it does indeed include the full size of the gzip binary in the metric. Weird. The competition is specific to one corpus of test data; it doesn't include testing on other data. If the size of the program weren't included, you could hard-code all of the test data into it and claim victory with an infinite compression ratio. Fun fact: the idea of using an AI language model as compression has existed since at least 1988. It was mentioned in passing by Vernor Vinge in his short story The Blabber.
